deserializePayload method

@override int deserializePayload(PlanControlBuilder builder, ByteData byteData, Endian endianness, int offset,)

Call to deserialize only the payload, no header. The Builder is to allow passing the message to build into. returns a int with a serialized size

Implementation

@override
int deserializePayload(imc.PlanControlBuilder builder, ByteData byteData,
    Endian endianness, int offset) {
  var byteOffset = offset;

  // field type
  builder.type = imc.PlanControlEnumType(byteData.getUint8(byteOffset));

  byteOffset += 1;
  // field requestId
  builder.requestId = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  // field planId
  var planIdSSize = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;

    planIdDData[i] = byteData.getUint8(byteOffset++);
  }
  var planIdDecoded = utf8.decode(planIdDData);
  builder.planId = planIdDecoded;
  // field flags
